Based on the cutting tools of the girl's body and the wood chips left on it, Officer Wang judged that the killer was most likely a carpenter.

When he found Wang Da's house in the wood processing shop, he found that Wang Da had been brutally killed and dismembered in his home.

Judging from the circumstances at the scene, the murderer changed into clean clothes at Wang Da's house and fled the crime scene after killing Wang Da.

The facts of the case are clear, but what was the motive for the killing?

What was Wang Da's motive for strangling the five-year-old girl and burying her body? What was the murderer's motive for killing Wang Da?

What is the relationship between Wang Da and this five-year-old girl? How did the bruises on the girl's body come about?

Perhaps the killer was the father of the five-year-old girl, who had come here to avenge his daughter.

Of course, this is just a conjecture by Officer Wang based on the situation at the scene.

There are still many questions to be answered in this case, and if these questions are not clarified, this case will never be clear.

This wood processing shop has neighbors on the left and right, and they have been neighbors with Wang Da for a long time, so they must know something about him.

In traditional criminal investigation, investigative visits are an indispensable and very simple and effective way. An eyewitness can directly change the direction of the case, and a word from an eyewitness is sometimes more effective than the clues directly brought to us at the scene.

The left and right neighbors of the wood processing shop are a car repair shop and a driver who runs long-distance transportation, and the specifications of the houses are the same as Wang Da's house, which is a small bungalow with a large yard in front.

This is the most traditional mode of living, separated from the neighbor's house by a low red brick wall. Distant relatives are not as good as close neighbors, and the relationship between neighbors is still relatively close.

Investigative visits are not the interrogation of suspects, and the police do not disturb the normal life of residents unless necessary. It was seven o'clock in the morning, and there was a sound from the car repair shop next door, and two large black painted iron doors were opened with a creaking sound.

Officer Wang immediately walked to the car repair shop next door, the boss just opened the door, and he was stunned when he saw Officer Wang walk into the yard. Did you think it went so well today? As soon as the doors opened, business came to the door.

But what he didn't expect was that the person who came to the door was not a guest who repaired the car, but a criminal policeman.

What he didn't expect was that a murder had just happened in the house of his neighbor Wang Da, who was across the wall from him.

"Police."

Officer Wang didn't say a word, and directly showed him his police ID.

The owner of this auto repair shop is called Liu Keming, who has been driving car maintenance here for more than ten years, and his father is doing this, so he also does this. It is very common for children to inherit their father's business in this kind of handicraft.

Liu Keming and Wang Da have been neighbors for seven years, and seven years is enough for a person to become friends with the neighbors who get along with each other day and night, and it is enough for two strangers to become familiar and understand each other.

Ordinary people are stunned when they see the police coming to the door, and Liu Keming is no exception, but his first reaction is not that the police come to the door to find out what to do, but that the police car broke down and the police came to repair the car.

"Do you know Wang Da?" Officer Wang asked him.

Liu Keming was stunned again, fixed his mind, and asked Officer Wang with some curiosity: "What's wrong with Wang Da?" Did he break the law? ”

Although Liu Keming did not directly answer Officer Wang's question, his question already explained everything. The two of them not only knew each other, but they knew each other very well.

"Does Wang Da usually live alone?" Officer Wang asked seriously.

Liu Keming replied lightly: "No, he has a daughter." ”

"He's married?" Officer Wang was a little puzzled.

Because the police did not see any items belonging to women in Wang Da's home, and Officer Wang had already investigated the carpenter in Ningzhou City before coming to investigate, the household registration information stated that Wang Da was unmarried.

But there are many things in this world that are not in accordance with the regulations, and it is very likely that Wang Da did not register his marriage, dated an illegal wife, and gave birth to a child.

Liu Keming shook his head and denied: "He is not married." ”

"He has a lover?" Officer Wang asked.

Liu Keming still shook his head and denied: "No." ”

"Then how can there be children?" Officer Wang was puzzled.

Liu Keming smiled and told Officer Wang about his old neighbor, Wang Da-

"I've known Wang Da for seven years, he's Chinese New Year's Eve eight years now, let alone marriage and lovers, I've never seen a woman stay overnight here. He seems to have something wrong here, otherwise why doesn't he have a wife at thirty-eight? Liu Keming pointed to his head and signaled that Officer Wang Da's head was sick.

Subsequently, Liu Keming continued: "But, I've known him for so long, I don't think he looks like he's sick, sometimes I suspect that he is gay, or he was hurt by a woman when he was young, or he was divorced......"

Liu Keming guessed vigorously that Officer Wang did not interrupt him, but just listened silently.

Liu Keming thought for a while, and suddenly said: "About a month ago, there was suddenly a little girl in his family, and I saw that little girl was four or five years old, I thought it was the child of his relative." One day I was sweeping the yard and saw him sweeping the yard too, so we talked for a while across the wall.

He said that the child was adopted by himself from the orphanage, because he was getting older and unmarried, and he did not even have a person to support him in his old age. I also joked with him that he should find a companion too, or he should live alone, and if something happens, no one in the smelly house will know.

Wang Da smiled and agreed with what I said, he said that he thought the same way, so he adopted a child. In those days, I saw the little girl calling Wang Da 'Dad', and I was quite happy, and Wang Da was also a father.

But I always suspected that the child was not adopted by him, but bought by him. ”

Liu Keming's words startled Officer Wang, and Officer Wang immediately asked him: "You said that he bought that child?" ”

Liu Keming hesitated for a moment, and asked Officer Wang with some caution: "If what I said is not right, I won't break the law, right?" ”

Officer Wang smiled and explained, "It's okay, you don't have to be legally responsible for what you say, just tell me everything you know." ”

Liu Keming thought for a while, and then said: "Wang Da has long had the idea of having a child, but how can he have a child without a wife?" Several times he made small talk to me and asked me if there was any way I could have a baby. I told him that if he wanted a child, he could go to an orphanage to adopt, but the adopter was not his own after all, and his feelings still needed to be cultivated.

Wang Da suddenly said a strange sentence to me: 'It doesn't matter if you have feelings or not, just be a child'. ”
